DAY 2/15 | Is Light a Wave or a Particle? Imagine throwing a tennis ball through a window. You expect it to leave one hole. Now imagine throwing a wave through the same window. It spreads out. Simple. For centuries, scientists believed light was a wave. Then they discovered something impossible. Sometimes light behaves like tiny particles called photons. Other times, it behaves exactly like a wave. It doesn’t choose one forever—it depends on how we observe and measure it. This discovery changed physics forever and became one of the foundations of Quantum Mechanics. The universe isn’t built on “either-or.” Sometimes, it’s both. Tomorrow: The experiment that shocked the scientific world—the Double-Slit Experiment. #QuantumMechanics #QuantumPhysics #ScienceExplained #Physics #photon
